If it is about knowing when exactly I am stopping gambling, that's what I can't foresee now. The only time I know that I am about to stop gambling is when I know that I am not that vibrant in analyzing games the way I did before. Once I notice such changes have been made in my body, I will peacefully stop gambling without minding the time it was(old or young age).
My life principle is never to stay put in something that I know that I can't keep on with, no matter how fun it is.
